The pump MAGNA is of the canned rotor type, i.e. pump and motor form an integral unit without shaft seal and with only two gaskets for sealing.
The pumped liquid lubricates the bearings.
In order to avoid problems in connection with disposal, great importance has been attached to using as few different materials as possible.
A pump with no maintenance requirements and extremely low Life Cycle Cost.

The pump is characterized by:
* Electronically Commutated Motor (ECM) with permanent magnet rotor
* Pump controller integrated
* Ceramic radial bearings
* Carbon axial bearing
* Stainless steel rotor can, bearing plate and rotor cladding
* Aluminium alloy stator housing
* Cast iron pump housing
* Protected against overload

The pump is a single-phased.
The motor does not require external motor protection

Grundfos MAGNA - part of Series 2000 pumps - feature automatic control
of differential pressure through adaptation of pump performance to actual
heat requirement without the need for connection of external components
Four control modes are available:
* AUTOADAPT (self-regulating from "one proportional pressure curve to another") to optimise comfort and reduce energy consumption to a minimum
* Proportional pressure
* Constant pressure
* Constant curve (available through external communication only)

The pump can communicate through
* Integrated clip-on optional Relay module (start/stop signal, alarm/feed-back signal)
* Integrated clip-on optional GENIbus module (start/stop signal, alarm/feed-back signal, 0-10 V analog input, control of twin-head pumps, and external forced control via inputs for Max. curve and Min. curve)
* Handheld remote control R100 (separate Grundfos product)
